Integration of LVM with Hadoop
In this blog, we are going to do two things: 🔅 Integrating LVM with Hadoop and providing Elasticity to DataNode Storage 🔅Increase or Decrease the Size of Static Partition in Linux. LVM (Logical Volume Manager) Logical volume management (LVM) is a form of storage virtualization that offers system administrators a more flexible approach to managing disk storage space than traditional partitioning. This type of virtualization tool is located within the device driver stack on the operating system. It works by chunking the physical volumes (PVs) into physical extents (PEs). The PEs are mapped onto logical extents (LEs) which are then pooled into volume groups (VGs). These groups are linked together into logical volumes (LVs) that act as virtual disk partitions and that can be managed as such by using LVM. LVM is an amazing technique using which you can increase the storage of device on the fly , without loosing data, without shutting down the syste...
